Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing equipment, and in particular to a splash-proof aluminum profile drilling machine. Background Technology

[0002] Aluminum profile drilling machines are machining equipment specifically designed for drilling holes in aluminum profiles. During processing, the drill bit generates debris when drilling holes in the aluminum profile. Under the action of centrifugal force, some of the debris is flung away by the drill bit, affecting the cleanliness of the workbench and increasing the difficulty of cleaning. In addition, the flung debris may also injure the processing personnel. Therefore, there is a need for an aluminum profile drilling machine that can prevent debris from splashing, thereby protecting the personal safety of the workers and further improving the efficiency of cleaning operations. Utility Model Content

[0003] The purpose of this invention is to provide a splash-proof aluminum profile drilling machine, which aims to solve the problem of waste chips flying everywhere during the drilling process of existing drilling machines.

[0004] To achieve the above objectives, this utility model provides a splash-proof aluminum profile drilling machine, including a drilling machine body, a drill bit mounted on the drilling machine body, and a splash-proof component mounted on the drill bit. The splash-proof component includes a linkage frame, a sliding frame, a collection cover, and a dust collection unit. The linkage frame is mounted on the drill bit and can rise and fall together with the drill bit. A sliding groove is provided on the linkage frame, and the sliding frame is slidably mounted in the sliding groove. A limiting rod and a reset elastic element are provided in the sliding groove. The limiting rod is fixedly mounted in the sliding groove, and the sliding frame can slide on the limiting rod. The reset elastic element is sleeved on the limiting rod, with one end abutting in the sliding groove and the other end abutting against the sliding frame. A detachable collection cover is provided at the bottom of the sliding frame, and the collection cover can rise and fall together with the sliding frame. The dust collection unit is mounted on the linkage frame and is connected to the collection cover through a flexible hose.

[0005] Furthermore, the main body of the drilling machine is equipped with a guide rod, and the side of the linkage frame away from the drill bit is connected to the guide rod, and the linkage frame can slide on the guide rod.

[0006] Furthermore, the collection cover includes an outer cover and an inner cover. The inner cover is inverted conical in shape and is installed inside the outer cover. The outer cover is detachably connected to the sliding frame, and at least two sets of laser positioning components are provided on the outer cover.

[0007] Furthermore, the laser positioning component includes an extension rod, a swing arm, and a linear laser emitter. The extension rod is fixedly installed on the outer cover, and a swing arm is provided at the end of the extension rod. The swing arm is connected to the extension rod through a locking knob, and a linear laser emitter is provided at the end of the swing arm. The linear laser emitter is connected to the swing arm through a locking knob.

[0008] Furthermore, the outer cover has guide rails, on which arc-shaped covers are slidably mounted; multiple sets of air inlet holes are evenly arranged at the bottom of the outer cover.

[0009] Furthermore, the main body of the drilling machine is equipped with a lifting platform, on which a clamping assembly is installed. The clamping assembly includes a base, a clamping plate, an auxiliary guide rod, and a handle threaded rod. The base is installed on the lifting platform, and a fixing plate is installed on the base. The auxiliary guide rod and the handle threaded rod are both installed on the base. The clamping plate is installed on the auxiliary guide rod and can slide on the auxiliary guide rod. The handle threaded rod is used to move the clamping plate closer to or away from the fixing plate.

[0010] Furthermore, the base has a slot at the bottom, and the lifting platform has a corresponding discharge chute with an inclined shape.

[0011] Furthermore, the dust collection unit includes a negative pressure drive component, a mounting base, and a waste box. The mounting base is fixedly installed on the linkage frame, the negative pressure drive component is fixedly installed on the mounting base, and the mounting base is provided with a mounting seat for installing the waste box.

[0012] Furthermore, the waste box is equipped with clips, and the mounting base is equipped with corresponding clip slots.

[0013] The anti-splash aluminum profile drilling machine provided by this utility model, compared with the prior art, allows the linkage frame to drive the collection cover to descend together with the sliding frame during aluminum profile drilling operations. The arc-shaped cover on the collection cover will first contact the workpiece, isolating the drilling position from the operator. As the drill bit continues to descend, it contacts the workpiece to drill, and the generated waste chips will be covered by the collection cover. The negative pressure drive component creates a negative pressure in the collection cover, sucking the waste chips in the collection cover into the waste box, reducing the impact of splashed waste chips on the operator. At the same time, the waste chips in the waste box can also be easily collected and cleaned by the operator. Attached Figure Description

[0035] The present invention will be described in detail below with reference to specific embodiments.

[0036] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0037] like Figures 1 to 14 As shown, this utility model provides a splash-proof aluminum profile drilling machine, including a drilling machine body 1, a drill bit 10 disposed on the drilling machine body 1, and a splash-proof component 2 disposed at the drill bit 10; the splash-proof component 2 includes a linkage frame 20, a sliding frame 21, a collection cover 22, and a dust suction unit 23. The linkage frame 20 is mounted on the drill bit 10 and can rise and fall together with the drill bit 10; a slide groove 200 is provided on the linkage frame 20, and the sliding frame 21 is slidably installed in the slide groove 200; a limit rod 201 is provided in the slide groove 200 and... The reset elastic element 202 and the limiting light rod 201 are fixedly installed in the slide groove 200, and the sliding frame 21 can slide on the limiting light rod 201; the reset elastic element 202 is sleeved on the limiting light rod 201, one end of the reset elastic element 202 abuts in the slide groove 200, and the other end abuts on the sliding frame 21; a detachable collection cover 22 is provided at the bottom of the sliding frame 21, and the collection cover 22 can be raised and lowered together with the sliding frame 21; the dust suction unit 23 is installed on the linkage frame 20, and the dust suction unit 23 is connected to the collection cover 22 through the hose 26.

[0038] With the above design, when drilling is required, the linkage frame 20 rises and falls together with the drill bit 10, ensuring that the sliding frame 21 moves synchronously with the collection cover 22 and the drill bit 10. As the drill bit 10 contacts the workpiece and begins drilling, the waste generated during drilling will be covered by the collection cover 22. At the same time, the dust suction unit 23 absorbs the waste through the hose 26, preventing the accumulation of waste in the collection cover 22 from affecting the surface accuracy of the workpiece. The waste collected by the dust suction unit 23 can also facilitate subsequent collection and cleaning operations, improving cleaning efficiency. As the drill bit 10 continues to penetrate deeper into the workpiece, the collection cover 22 will directly press against the workpiece. As the drill bit 10 continues to penetrate deeper, the collection cover 22 pressing against the workpiece no longer moves with the drill bit 10, but slides in the slide groove 200 with the sliding frame 21, preventing the collection cover 22 from continuing to move downward and damaging the workpiece or the drill press body 1.

[0039] The limiting rod 201 in the slide 200 can make the sliding frame 21 slide more smoothly in the slide 200. When the linkage frame 20 rises with the drill bit 10, the linkage frame 20 rises together with the drill bit 10. Under the action of gravity and the reset elastic element 202, the sliding frame 21 will automatically retract to the bottom of the drill bit 10 and retract to the position where the collection cover 22 covers the bottom of the drill bit 10, so as to prevent the operator from being accidentally scratched by the sharp part of the bottom of the drill bit 10 when not working.

[0040] In this embodiment, the reset elastic element 202 is preferably a spring.

[0041] In this embodiment, a bearing is provided at the connection between the linkage frame 20 and the drill bit 10 to ensure that the linkage frame 20 can rise and fall together with the drill bit 10 while not being affected by the rotation of the drill bit 10.

[0042] In this embodiment, a guide rod 3 is provided on the main body 1 of the drilling machine, and the side of the linkage frame 20 away from the drill bit 10 is connected to the guide rod 3, and the linkage frame 20 can slide on the guide rod 3.

[0043] Through the above design scheme, the guide rod 3 can guide the movement direction of the linkage frame 20, ensuring that the linkage frame 20 can be raised and lowered vertically.

[0044] In this embodiment, the collection cover 22 includes an outer cover 221 and an inner cover 220. The inner cover 220 is inverted conical in shape and is installed inside the outer cover 221. The outer cover 221 is detachably connected to the sliding frame 21. At least two sets of laser positioning components 24 are provided on the outer cover 221.

[0045] Through the above design scheme, the inverted cone-shaped inner cover 220 can guide the outside air flow to the connection between the drill bit 10 and the workpiece, and can also dissipate heat from the workpiece and the drill bit 10 while rolling up the splashed debris; the blown debris rotates inside the outer cover 221 and then enters the dust suction section 23 under the guidance of the hose 26.

[0046] In this embodiment, the detachable connection between the outer cover 221 and the sliding frame 21 is a pin connection. A sliding seat is provided on the outer cover 221, and a sliding groove is provided on the sliding frame 21. Both the sliding seat and the sliding groove are provided with pin holes. During assembly, the operator can first align the sliding seat with the sliding groove, and then insert the pin after the pin holes are aligned to lock the outer cover 221 onto the sliding frame 21. When it is necessary to replace the drill bit 10, the collection cover 22 covering the drill bit 10 will inevitably interfere with the replacement operation. When it is necessary to remove the collection cover 22, the operator only needs to pull out the pin and slide the collection cover 22 downward to complete the removal work, which facilitates the replacement of the drill bit 10.

[0047] In this embodiment, the laser positioning component 24 includes an extension rod 240, a swing rod 241, and a linear laser emitter 242. The extension rod 240 is fixedly installed on the outer cover 221. The swing rod 241 is provided at the end of the extension rod 240. The swing rod 241 is connected to the extension rod 240 through a locking knob 243. The linear laser emitter 242 is provided at the end of the swing rod 241. The linear laser emitter 242 is connected to the swing rod 241 through a locking knob 243.

[0048] With the above design scheme, the linear laser emitter 242 in the two sets of laser positioning components 24 can emit linear lasers. The two linear lasers will converge at the landing point of the drill bit 10, which makes it convenient for the operator to position the landing point to fix the workpiece. Since the installation position and related settings of the linear laser emitter 242 are existing technologies, they are not described in this embodiment.

[0049] In this embodiment, a guide rail 223 is provided on the outer cover 221, and an arc-shaped cover 25 is slidably installed on the guide rail 223; multiple sets of air inlet holes 222 are evenly provided at the bottom of the outer cover 221.

[0050] Through the above design scheme, the guide rail 223 allows the arc-shaped cover 25 to rise or fall freely on the outer cover 221. Under the action of gravity, the arc-shaped cover 25 will slide down below the outer cover 221. When the arc-shaped cover 25 is below the outer cover 221, the height of the arc-shaped cover 25 will be lower than the height of the drill bit 10. Therefore, before the drill bit 10 drills into the workpiece, the arc-shaped cover 25 will first contact the surface of the workpiece to isolate the drilling point from the operator in advance. When the drill bit 10 continues to press down, the arc-shaped cover 25 remains stationary, the collecting cover 22 continues to move down, and the arc-shaped cover 25 slides along the guide rail 223 until the collecting cover 22 abuts against the upper surface of the workpiece. When the collection cover 22 is pressed against the upper surface of the workpiece, the airflow inside the collection cover 22 will be reduced because the lower part of the collection cover 22 is blocked by the workpiece. This will not be conducive to the dust collection part 23 picking up the waste. The air inlet 222 at the bottom of the outer cover 221 can increase the airflow and ensure that the flowing air has enough kinetic energy to drive the waste into the dust collection part 23.

[0051] In this embodiment, the curved cover 25 is made of highly transparent tempered glass.

[0052] In this embodiment, a lifting platform 4 is provided on the main body 1 of the drilling machine, and a clamping assembly 5 is installed on the lifting platform 4. The clamping assembly 5 includes a base 50, a clamping plate 51, an auxiliary guide rod 52, and a handle threaded rod 53. The base 50 is installed on the lifting platform 4, and a fixing plate is provided on the base 50. The auxiliary guide rod 52 and the handle threaded rod 53 are both installed on the base 50. The clamping plate 51 is installed on the auxiliary guide rod 52, and the clamping plate 51 can slide on the auxiliary guide rod 52. The handle threaded rod 53 is used to move the clamping plate 51 closer to or away from the fixing plate.

[0053] Since the lifting platform 4 and the clamping assembly 5 are existing technologies and not improvements of this patent, they are not described in detail in this embodiment.

[0054] In this embodiment, the distance between the two sets of linear laser emitters 242 is greater than the width of the lifting platform 4, so as to avoid the linear laser emitters 242 from hitting the lifting platform 4 when descending.

[0055] In this embodiment, the bottom of the base 50 is provided with a slot 54, and the lifting platform 4 is provided with a discharge trough 40 corresponding to the slot 54. The discharge trough 40 is inclined.

[0056] With the above design, the slot 54 at the bottom of the base 50 allows fallen debris to fall directly into the discharge chute 40. The inclined discharge chute 40 facilitates cleaning. Operators can directly aim the air gun at the higher part of the discharge chute 40 and use high-pressure airflow to blow the debris out along the inclined discharge chute 40. Operators can directly place the trash can at the lower part of the discharge chute 40 to collect the debris blown out by the high-pressure airflow. Since most of the debris is collected by the collection hood 22 and sucked in by the suction unit 23, the debris falling into the discharge chute 40 is mostly a small amount of debris that falls after drilling through the workpiece, and will not affect the cleanliness of the working area.

[0057] In this embodiment, the dust collection unit 23 includes a negative pressure drive component 232, a card holder 230, and a waste frame 231. The card holder 230 is fixedly installed on the linkage frame 20, and the negative pressure drive component 232 is fixedly installed on the card holder 230. The card holder 230 is provided with a mounting seat for installing the waste frame 231. The waste frame 231 is provided with a waste chamber 2310, and the waste chamber 2310 is provided with an air intake window 2313 that communicates with the negative pressure drive component 232. The waste chamber 2310 is provided with an isolation sponge 2311.

[0058] In this embodiment, a buckle 2312 is provided in the waste frame 231, and a slot 2300 corresponding to the buckle 2312 is provided on the mounting base.

[0059] The negative pressure drive component 232 is preferably a miniature vacuum pump. Through the above design, the negative pressure drive component 232 can generate negative pressure in the waste chamber 2310. This negative pressure draws waste debris from the collection hood 22 into the waste chamber 2310. The isolation sponge 2311 in the waste chamber 2310 ensures airflow while preventing waste debris from entering the negative pressure drive component 232 through the suction window 2313, thus protecting the negative pressure drive component 232 from damage. When there is too much waste debris in the waste frame 231, the operator needs to remove the waste frame 231. To remove the waste frame 231, the operator can press the latch 2312 to disengage it from the slot 2300, and then pull the waste frame 231 downwards to remove it directly.

[0060] The anti-splash aluminum profile drilling machine provided by this utility model, compared with the prior art, allows the linkage frame 20 to drive the collection cover 22 to descend together through the sliding frame 21 during aluminum profile drilling operations. The arc-shaped cover 25 on the collection cover 22 will first contact the workpiece, isolating the drilling position from the operator. As the drill bit 10 continues to descend, it contacts the workpiece to drill, and the generated waste chips will be covered by the collection cover 22. The negative pressure drive component 232 creates a negative pressure in the collection cover 22, sucking the waste chips in the collection cover 22 into the waste frame 231, reducing the impact of splashed waste chips on the operator. At the same time, the waste chips in the waste frame 231 can also be easily collected and cleaned by the operator.

[0061] Where there is no conflict, the above embodiments and features can be combined with each other.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
